LUGIEN P. HART, OF PHILADELPHIA, PENNSYLVANIA.

DYEING APPARATUS.

To all whom it may concern Be it known that I, LUOIEN P. HART, a citizenof the Republic of France, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a certain new anduseful Improvement in Dyeing Apparatus, of which the following is aspecification.

My invention relates to a new and useful improvement in dyeingapparatus, and has for its object to provide an exceedingly simple andeffective device of this character in which the material to be dyed willbe drawn over rolls and submerged in a vat of dye, or by placlng soapllquor instead of.

dye in the dyer said dyer can be used for ungumming of silk goods.

Another object of my invention is to so draw the material over first oneroll and then another that the dye will be evenly taken up by the goodspreventing them from becoming streaked or spotted, and preventing suchmaterial as silk goods from becoming creased, rubbed or chafed in thedyeing process.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, 1 will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in whioh Figure 1 is aside elevation of my improvement. Fig. 52, a plan view. Fig. 3, an endview. Fig. t, a view in elevation of one of the rolls. Fig. 5, anenlarge view of a portion of one end of the rolls showing the device forattaching the goods thereto. Fig. 6, a sectional view of the vat and oneof the rolls therein showing the means for placing the dye in the vatand adding hot water, and Fig. 7 a section at the line m-x of Fig. 6,looking in the direction of the arrows.

In carrying out my. invention as here embodied, A represents a vat, inwhich are journaled a number of rolls B and C, one end of each of theirshafts B and G eX- tending through the openings D in the vat, which arethen closed by the packings E.

Specification of Letters Patent.

Application filed April 13, 1909.

Patented J uly 23,1912.

Serial No. 489,638.

On the outer ends of the shafts B. and C are slidably secured the clutchmembers F and G, which engagewith the clutch members H and'l, which areoperated in some suitable manner, one of the ways for doing the samebeing hereinafter described.

To the clutch member H is attached the bevel gear J and the drivingpulley K, and to the clutch member I is attached the bevel gear L.Meshing with these bevel gears are the bevel pinions M and N, mountedupon the shaft 0, which is ournaled in the bearings P. On the shaft 0 isalso mounted the driven pulley Q, over which runs a belt from somesuitable source of power.

From the foregoing description it will be seen that when the pulley Q isdriven it will revolve the shaft O, which will do likewise with theclutch members H and I, through the medium of the bevel gears J and Land the pinions M and N, so thatwhen either of the clutch members F andG are brought into engagement with its adjacent clutch member, one ofthe rolls B or C will be revolved.

In order that-one clutch member will be brought into engagement with itsadjacent member when one of the other clutch members is disengaged fromits adjacent clutch member, I provide the brackets R and S, to which arepivoted the'bell crank levers T one end of each of which is attached toone of the clutch members F or G, the other ends being pivoted to therod U, so that when said rod is moved in one direction or the other oneof the clutch members F or G will be withdrawn from its adjacent member,while the other one will be brought into engagement with its adjacentclutch member.

Mounted on the shafts B and G are the brake wheels V, around a portionof the periphery of which extends the brakes W,

the lower ends being pivoted to the vat or brake will be removed fromthe brake wheel on the roll shaft, to which is secured the clutch thatis put into engagement.

In each of the rolls is formed a groove D, in which is mounted theroller the ends of the shaft thereof being journaled in the bracketplate I attached to the sides of the roll by screws G or other suitablesecuring means. On the roller E are placed a number of pins H so thatthey are in alinement with one another from one end of the roller to theother, and to these are attached the end of the goods to be dyed, andwhen the end of said goods has been placed over these pins the roller isturned over by the handle I secured to the roller or its shaft, at whichtime the pins will rest within the groove D, and in order that thesepins may be held within the groove while the machine is in motion, Isecure to the side of the roll a spring catch J, which will spring overthe handle I when said handle is moved downward.

In placing additional coloring pigment in the vat while the goods are inthe same it is necessary to keep said coloring pigment away from thegoods until it has been thoroughly mixed in the dye already in the vat,and in order that this may be done, I provide a pipe K which extendsdownward into the vat, then at right angles thereto into the interior ofthe rolls, said pipe leading from a funnel L in which is placed thecoloring pigment. As the said coloring pigment leaves the pipe K it willbe inside of the rolls, and as the roll is being revolved it willagitate the dye, thoroughly mixing the coloring pigment with thecontents of the vat.

In order that the dye may be kept at a boiling temperature, I providethe steam pipe M which passes downward into the vat at one side thereof,then lengthwise of the vat between the rolls, as indicated by N, andthat portion of the pipe which lies along the bottom of the vat betweenthe rolls will have a number of outlets. To prevent this steam coming incontact with the goods upon the rolls which would streak the goods, Iprovide the battle plates 0, which form the arc of a circle, which aresituated between the steam pipe and the rolls.

After the goods have remained in the dye a suflicient length of time theend which is attached to the roll B is removed and carried over theroller P, then under the lower wringer roll Q, under which is placed thetray It. The goods then pass between the wringer roll Q and the upperwringer roll S, which will press the water and dye from the goods, saidwringer rolls being re volved from the driving pulley K through themedium of the belt E, which passes over said driving pulley and thepulley U attached to the shaft of one of the wringer rolls. In orderthat the wringer rolls Q, and S may be kept constantly pressed togetherI provide a bracket 1, secured to the vat, to which is pivoted one endof the lever 2, at 3, and on this lever is slidably secured the yoke 4having an upwardly extending stack 5, in which may be placed one or moreweights 6. Pivoted to the crane 7 is another lever 8, the outer end ofwhich is connect-ed with the lever 22 by the link 9, said lever 8 havingan adjusting screw 10 pass ing through it, the lower end of which restsagainst the bearing 11 of the wringer roll S. From this description itwill be seen that the weight 6 on the end of the lever 2 will draw theend of said lever downward, which will do likewise with the lever 8through the medium of the link 9, which will cause the wringer roll S tobe constantly pressed against the wringer roll Q.

While the goods are passing through the wringer rolls a stream of coldwater is played thereon from the pipe V, so that the goods will becooled enabling them to be handled. After the goods have passed throughthe wringer rolls they run over the roll IV, then downward. through thefolding rolls Y, which are operated to and fro by the crank Z, which isattached to the crank wheel Z In practice one end of the goods itattached to one of the rolls B or C by means of the attaching device,then that roll is caused to revolve, drawing the goods through the dye,and when this operation has continued for a while this roll is broughtto a standstill, so that the rear or last end of the goods is at the topof the roll. This end is then attached to the opposite roll and bymoving the brake A and the clutch rod U in the opposite direction theroll to which the rear end of the clutch is attached will be caused torevolve, and at the same time the brake will be applied to the otherroll, so that it cannot revolve faster than the roll which is taking thegoods, so that said goods will not become mussed or wrinkled.

When the goods has been drawn through the dye first on one roll and thenthe other in the manner described, for a sufficient length of time tosecure the right shade, it is then drawn through the wringer and overthe folder, at which time it will be ready to be removed to a convenientdrying place.

Of course I do not wish to be limited to the exact details ofconstruction here shown as these may be varied within the limits of theappended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is-

1. Dyeing apparatus comprising a tank for containing dye, imperforateopen ended cylinders for conducting the material to be dyed into contactWith the dye, the interiors of said cylinders communicating with saidtank at points removed from the material, and means for conducting thedye to a point within the cylinder whereby a thorough mixing isattained.

2. Dyeing apparatus comprising a tank adapted .to contain dye,imperforate cylinders adapted to be submerged in the dye in said tankand having open ends, and means for introducing a fresh supply of dyeinto said cylinders.

In testimony whereof, I have hereunto aflixed my signature in thepresence of two 15 Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents, Washington, D. G.
